FIRE-HYDRANT.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed March 3o, 191s. serial No. 225,738.

To all whom t may concern.'

Be it known that I, ERNEST CHARLAND, a citizen of the United States,residing at Indian Orchard, in the county of I'Iampden and State ofMassachusetts, have invented new and useful Improvements inFire-Hydrants, of which the following is a specification.

This invention relates to improvements in ire hydrants, the object ofthe invention being to provide an improved form of tire h ydrant whichembodies a valve operating rod having a detachable upper member which isarranged in the post, so that when the post becomes accidentally brokenoff, said upper member of the said rod separates from the lower portionof the rod and the valve remains closed, thereby preventing any flow ofwater, and furthermore, should the post become accidentally broken oli7while the water is flowing or in use, the lower portion of the rod canbe used for closing the valve.r and thus prevent any loss of water.

Another object of the invention is to provide an improved form of firehydrant which embodies a stand pipe comprising a lower member and anupper member and also embodying a ring which is detachably securedbetween said upper and lower members of the stand pipe, the said ringproviding a bearing for the valve operating rod, and means to coact withthe ring to prevent the said rod from moving vertically in the eventthat the post should be broken off and the upper member of the roddetached from the lower member thereof.

With the above and other objects in view the invention consists in theconstruction, combination and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawing Figure 1 is a vertical central sectionalview of a tire hydrant constructed and arranged in accordance with myinvention.

Fig. 2 is a horizontal sectional view of the same on the plane indicatedby the line 2-2 of Fig. 1.

Fig. 3 is a detailed sectional view of the joint between the members ofthe valve operating rod.

Fig. 4 is a similar view of the ring.

In the embodiment of the invention shown in the accompanying drawing,the body of the hydrant is indicated at 1, the valve at 2, the sternpipe at 3, the pest at 4,

and the rod for operating the valve is indicated at 5.

The stand pipe comprises a lower member G and an upper Inelnber 7. Thelower member is bolted at its lower end to the upper Side of the body asat 8 and the upper member has its upper end bolted to the lower end ofthe post as at 9. A ring l() is interposed between the upper end of thelower member G and the lower end of the upper member 7 and said membersand said ring are secured together by means of boltsll. The ring hasopenings therein vto permit the flow of water therethrough and is alsoprovided with a central bearing l2 through which the rods 5 eX- tend.The rod may be turned freely in the bearing but is prevented from movingvertically by means of a pair of collars 114 which are secured on therod and one of which bears on the upper side of the ring, the othercollar bearing against the lower side of the ring as shown.

The rod comprises a lower member 15 which is arranged in the stand pipeand in the body of the hydrant and an upper member 16 which is arrangedin the post as shown. Said upper and lower members of the rod aredetachably brought together as at 17. To form the said joint one of therod members is pointed as at 18 and the other is iecessed as at 19 toreceive the said pointed en The members of the rod are also provided attheir meeting ends with separable clutch members 20, 21, each clutchmember being provided with teeth 22 to engage in the spaces of the otherclutch member.

In the event that the post of the hydrant should be broken off byaccident, the upper member of the valve operating rod separates from thelower member thereof, at the joint, and the lower member of the rodremains in place, thereby preventing any loss of water. Furthermoreshould the post be broken oil' while the water is flowing or in use, thelower member of the rod can then be turned to close the valve and cutoff the low of water from the hydrant.

While I have herein described and shown the preferred form of myinvention I would have it understood that changes may be made in theform, proportion and construe tion of the several parts, withoutdeparting from the spirit of my invention and within the scope of theappended claim.

Having tlius described my invention I eleimz In a, fire hydrant, a body,:i stand pipe Connected to the bodyT and eomprising :i lower member anden upper member, e ring bolted between the lower and upper members oftbe stand pipe und having e bearing; e post bolted to the upper end ofthe upper stand pipe member und provided with a bearing neer its upperend, and e valve operating rod comprising e lower member and an uppermember, seid lower member being arranged in the body and stand pipe andin Gopies of this patent may be obtained for five cents each, byaddressing the the bearing of the said ring, sind lower member havingmenne eoueting with seid ring to prevent vertieel movement of seid lowerrod member, and said upper rod member being arranged in the post`mounted in tl'ie bearing of the poet und detaehebly Vjointed et itslower end to the said lower rod member, the Said rod members beingprovided at their meeting ende with separable clutch members to releasethe upper rod member in the event that the post should become brokenoff.

In testimony whereof I affix my signature.
